Joseph John Kohn (born May 18, 1932) is a Professor Emeritus of mathematics at Princeton University, where he does research on partial differential operators and complex analysis. ==Life and work== Born to a family of a Czech architect Otto Kohn of Jewish origin, he emigrated with his family to Ecuador in 1939 after the Germans invaded Prague where he attended Colegio Americano de Quito, and to the United States in 1945, where he attended Brooklyn Technical High School. He studied at MIT (S.B. 1953) and at Princeton University, where he obtained his PhD in 1956 under Donald Spencer ("A Non-Self-Adjoint Boundary Value Problem on Pseudo-Kähler Manifolds"). Later he was at the Institute for Advanced Study during 1957/58 (and again 1961/62, 1976/7, 1988/89). In 1956/57, he was an Instructor in Princeton. In 1958, he was Assistant Professor, in 1962 Associate Professor and in 1964 Professor at Brandeis University, where he also served as Chairman of the Mathematics Department (1963-1966). Since 1968, he is a Professor at Princeton University, where he served as Chairman in 1993-96. He was a visiting professor in Harvard (1996/7), Prague, Florence, Mexico City (Centro de Estudios del IPN), Stanford, Berkeley, Scuola Normale Superiore (Pisa), Rome, Buenos Aires, and at IHES. His work focuses, among other things, on the use of partial differential operators in the theory of functions of several complex variables and microlocal analysis. Kohn was a Sloan Fellow in 1963 and a Guggenheim Fellow on 1976/77. From 1976 to 1988, he was a member of the editorial board of the Annals of Mathematics. In 1966 he was an invited speaker at the International Mathematics Congress in Moscow ("Differential complexes"). He has had at least 65 doctoral descendants. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Joseph J. Kohn」の詳細全文を読む スポンサード リンク
